Worked Solution & Example Answer:The graph of $y = \arccos x$ is shown - AQA - A-Level Maths Mechanics - Question 1 - 2021 - Paper 3
Step 1
State the coordinates of the end point P
Answer
The end point P corresponds to the maximum value of the function, which occurs at the point where . The value at this point is . Therefore, the coordinates of the end point P are . Circling this answer is important to indicate it as the correct choice.
